This is a set of 10 thick inner envelopes, suitable for both celebratory and condolence occasions. I bought these a few days ago because I wanted spares in case I made a mistake or got one dirty. This size is hard to find, so I bought a set of 100. I have too many, so I'm selling some. I'm listing these with almost no profit, just covering shipping and fees. They are plain white and do not have adhesive tape. They are exactly the kind of envelopes that go inside congratulatory envelopes. You can also use these on their own when giving a tip or money. Thank you.
